. Be it known that I, HERBERT Ha CBAMER, ot Aspen, in.A the, county4 ofPitkin andzState of. Co brado, have invented certain new and..

lusefulA Improvemente inValves; and. I do hereby declarethe following tovbe a full, clear, andiexactfdescription o .the invention, suchastwilLenable .othersskilledinthefart to.y which it to;` makeand. useythe same.. The primary o4 ofthis invention is toprovide improve means:forv removably olding a valve seat in place withine its casing; andfurther objects are to hold such seat by the same means that secures thepartsvofl thacasing together i, in'. simplifjr landcheapen y the. valveseat to. be reversed; to protect. the contactin 4or engaging surfaces ofythe valve disk an seat from j by rust. ete.; Yand toallow the inletsallid outlets to kbe positionedl at differes. The mvention will behereinafter fully'set forth and particularly Vpointed vout in theclaims.. j I l 'In' .the accompanying drawings, Figure 1 is.

a vertical. sectional view of v a `valve embodying my-invention... Fig.2 is a similar view at right angles. Figs. 'g'3 4. :and 5 show slightmodifications. V6 is abottom plan view of the valve disk. Fig, 7 1s asection on line 7f3?, elevation.

Referringto the drawings, 1 designates a lcasing which in Figs. 1, 2 and3 I have shown as being composed of two parts 2 and 3, each having alateral branch/1, one servin as the inlet and the other as the outlet. 2of the Casin is formed at its top with a large threadefh openin toaccommodate a' nut 5 and packing glan 6 through which o erating stem 7of the valve-disk 8 is passed. e sai threaded opening is of diameterFig. 8. is, a fragmentary side 4 about corresponding to-the diameter ofthe chamber of casing part 2. In this latter part is formed, near thelower edge thereof, 4an inner annular shoulder '9 to accommodatevalve-seat. 10. This valve seat is of circular formation and is formedwith two ports '12 with which are desig'ned to coincide twocorresponding portsA 13 of valve disk 8. The valve seat 10 is shown inFigs. 1 and 2 as formed with a central threaded opening, the ends ofwhich are flared, and into which opening screws one end of a bolt 14,the other T e part the end thereof being projected through anopenmodification 1n the to be turned so as to .in'casing part at theaxialcenter ofthe it e,fa. nut 15 beingscrewed lon the outer.,projecting end. of such boltd By thls meansK thevalve seat andthe two v'are held in place by the same agencyto wit.:

thevalveseat. i that in all instances the valveseatshouldbe. reversible,nor is itnecessary thatthe casing be formed in twoparts. "In-Fig. .4: I`have z shown the casing as formed-'inone part,

the valve-seat as hayingde ending angular lu s 1.6 .to. engagetheheadgofanutted. bt 17,` which bolt will, asin the yformer inf stance,removably hold. 4 place. In Fig. 5 -I have-shown a further form ofA a.centrally threaded hub 18, depen Y' tromfthe underside of the valveseat, an withwhi'ch enthe valve seat-fin 5.x

I preferably of the two parts of the valve casing with squared portions20, such squared portions by engaging straight walls 20a vent anyaccidental turning of the two parts ofthe valve casing,

placethe inlet and outlet branches at different angles. While I prefer'to employ a single bolt engaging the valve seat and extending through anopening in the casing, yet it is manifest that, if desired or necessary,additional bolts may be ein loyed for engaging with the valve seat, sucbolts being-likewise extended through the casing. The valve-seat may beheld as against turning by lugs 2Gb engaging some de ending art thereof,as shoiilh in Fig. 5.

l) have shown the valve-disk 8 as formed in 'its working face withcountersunk circular and yet allow the parts is not reversible, but iti'sheld l the singlenutted bolt, and al.-

.part,.yet it is manifest that any ofthe meansJ the same means,

serving to pref recesses 21, the diameterb of each of which l equalsthat of the ports 12 in the valve seat,

' always protected oneby the other.

The advantages of my invention will be apparent. From what has been saidit will be seen that by locating the securing means axially of the valvethe parts of the casing may be turned so that their laterals will bepresented at different anglesz that is to say, they may be located atright angles or face in opposite directions, as shown in the drawings,or at points intermediate these two positions. .It will `also be notedthat the parts of the casing are held together by the same means thatretains the` valve seat in place; and also that by securing the valveseat by means readily accessible 'from the outside of the casingthe'valve seat may be readily removed for the pur. ose of filing, and,in some instances, reverse so as to present its unused face to the valvedisk.

I claim as my invention: l

1. valve casing havin an internal annular shoulder, a removabgle valveseat located wholly within the casing resting against such shoulder andconstructed so as to be capable of being reversed, and means forsecuring such valve seat in place comprising a bolt extended through thevalve casing.

2. A valve comprising a casing formed in two arts, a valve seat designedto it in one of said parts, and a sin le agency for engaging said valve,seat an projectlng through one of said arts for holding the seat and thetwo parts ci) the casing together.

3. A valve comprising a casing formed in two parts, one part having anannular shoulder, a valve seat designed to Jrit against such shoulder,and a bolt engaging the valve seat and projecting through one of theparts of the casing for holding the seat and the parts of the casingtogether.

4. A valve com rising a casing having an internal annular shoulder, avalve seat having a threaded opening at its center extend-` 'ing'therethrough, said valve seat being reversible, and a threaded boltengaging said valve seat and extended through the casing.l

5. A valve comprising a casing formed 1n two parts, each of the partshaving interlocking squared portions, one art vhaving an inner annularshoulder, a va ve seat designed to rest against said shoulder, and meansfor securing said valve seat and the parts of the casing comprisingabolt projecting through one ofthe parts ofthe casing.

' 6. A valve com rising a valve-seat having ports extending t erethroughand countersunk recesses in its face of a diameter'equal to said ports,and a valve-disk having'ports designed to coincide with those of thevalve seat and also having countersunk recesses correslponding to thoseofthe valve seat.

7. valve comprising a valve-seat having opposite] arranged ports andcountersunk recesses in its face on the same circumference as the saidorts and midway thereof, and a valve-disk aving ports corresponding tothose of the valve seat, and on its face formed with countersunkrecesses designed to coincide with the orts of the valve-seat when thevalve is c osed, and with the countersunk recesses of the valve seatwhen the valve is opened.

In testimony whereof I have signed this speciication in the presence oftwo subscribingwitnesses.
